16 Driver Supported EFI Version Protocol
The Driver Supported EFI Version Protocol allows a UEFI Driver to specify the
version of the UEFI Specification it follows. The version information follows
the same format as the Revision field in the EFI_TABLE_HEADER
of the EFI
System Table. This feature is required for UEFI Drivers on PCI and other plug
in cards, but is only recommended for all UEFI Drivers.
